WILLIAM S. GRUNDY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALFTO OSWALD LEVER, OF SAME PLACE.

FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 525,599, datedSeptember 4, 1894.

Application filed March 31,1894. Serial 110.505.815. (No model.)

companying drawings, forming a part of this specification.

My invention relates to window sash fastening devices, and has for itsobject the con-' struction of the device in two parts, one of which isfastened to each of the sashes respectively, which co-operate byinterlocking with each other, to tighten and fasten together the upperand lower sashes. And to these ends my invention consists in a sash lockcomposed of two parts, one of which is fastened to the, lateral edge ofthe outer (or upper) sash, and is provided with a vertically projectinglink or its equivalent, in combination with the other element of thedevice which is composed of a journal bearing fastened to the lateraledge of the other (the inner) sash, and a shaft adapted to rotate in thebearing and carrying on one of its ends a curved hook, and provided atits other end with a lever arm so pivoted thereto that it will be freeto rotate either vertically or laterally when the hook shaft is rotatedthereby. Also in minor details of the device as hereinafter mentioned.

In the accompanying drawings illustrating my invention, Figure l is afront elevation with the lever raised and showing the looking plate onthe outer or rear sash in dotted lines. Fig. 2 is a like view with thelever down, and the rear sash raised to its normal position. Fig. 3 is aplan view of the same position of the parts as shown in Fig. 2 exceptthat the lever is drawn outwardly into its second position therebylocking the device.

The flat edges A and B of a pair of sashes, represented in plan view inFig. 3 have attached to the edge A of the upper and outer sash, byscrews 61 or otherwise, by its flat surface a, a metallic plate a whichis provided with a central link or loop a, and in order that the lattermay not project too high above the surface of the plate the said plateis reing b therefor which is formed integral with the fastening plate I)secured to the sash edge B by screws 6 or otherwise. The journal bearingbis slotted curvilinearly at b in which plays the pin I) mounted on theperiphery of the shaft 0, the eifect of which is to move the shaftlongitudinally as it is rotated, outward from the plane of the hook linka and thus allow the outer sash to be moved freely up or down whendesired. The shaft 0 is provided at one end with a hook c of such shapeand size relatively to the link or loop a as to pass freely into and outof the same at all times and in all relative positions of the device,when the shaft is rotated. The other and outer end of the shaft haspivoted to itby a pin 0 a lever arm 0 which has a square face rounded atone edge e to adapt it to be moved into the position shown in Fig. 2.

The operation of the device is as follows: Window sashes become looserelatively to each other, by wear and shrinkage, and produce a rattlingnoise, and the outer and upper sash. which is suspended by weightedcords drops from its normal position by reason of the wear andstretching of the cords. Both these objections are overcome by mydevice. The front elevation (Fig. 1) shows the outer and upper sash Adropped below the plane of the inner and lower sash B. In order to raisethis sash A to its normal position, tighten the two sashes in the windowframe, and lock the two together, the lever O is given a quarter turn tothe right as shown in Fig. 2 whereby the shaft 0 is partially rotatedand the hook c on the end thereof caused to engage with the loop or linka mounted by its retaining plate a on the outer sash,hence the latter israised until the edge A is flush with the edge B. If the lever C is thengiven a quarter turn in a horizontal plane, on its pivot pin 0 thusbringing it into the position shown in Fig. 3, it is apparent that thetwo sashes will be securely locked together. The reverse of these twomove ments of the lever O, successively, will have the efl'ect first tounlock the sashes, and secondly to release the hook c from engagementwith the link a and by the same movement the pinb on the shaft 0, movingin the curved slot b in the journal bearing b will cause the shaft 0 tomove outward longitudinally carrying it and its hook past the verticalplane of the sash A so that the latter may be raised or lowered asdesired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A sash lock consisting of a link or its equivalent adapted to besecured upon the vided at one end with a curved hook adapted 30 toengage with said link, a journal bearing for said shaft with means tosecure it to the edge of the opposite sash, and a locking lever 0 havinga rounded edge c and pivoted to said shaft in such manner that itsrounded 35 edge will be on the side opposite the hook when the parts'arebrought into locked position; substantially as described.

3. In combination forminga sash lock, the

link a and means to secure the same to the 4b edge of one of the sashes;and the partially V rotating shaft c provided with a. hook c' at oneend, the pivoted lever arm 0 at the other end, and a pin b on itsperiphery, the journal bearing 1) for said shaft and means to B0- .5

edge of onesash, and a curved hook adapted to engage therewith, a shaftupon which the hook is mounted, a journal-bearing for said shaft securedto the opposite and inner sash,

means between the journal-bearing and the shaft operating to cause thelatter to be res ciprocated longitudinally while being rotated, and alever pivotally mounted upon the free end of said shaft and operating topartially rotate the same; substantially as described.

2. In combination forming a sash look, a link or its equivalent securedto the edge of one sash, and a partially rotatable shaftprosubstantially as and for the purpose ca go scribed.

In testimony whereof I have hereunto 81- fixed my signature this 28thday of Februarjfl' WILLIAM S. GRUNDY. Witnesses:
